### Auto Ellipse Construction

The following table indicates the type of ellipse that is constructed when you select the specified inputs and choose the AUTO option. The order of the selected features is not important. If you select an incorrect input feature or features, Planner displays an error message and does not automatically construct the indicated feature type.

1. Access the Construct Ellipse dialog box (Insert | Feature | Constructed | Ellipse).

2. Select the Auto option from the list of options.

3. Select the desired feature(s) based on the table below.

4. Click the Create button.

The following lists the constructed feature that are created based on the selected input feature:

Any one Set = Best Fit Ellipse

Any one Ellipse = Reverse Ellipse

Any one Feature (except Ellipse /Set) = Cast Ellipse

Plane + Any Feature = Projected Ellipse

Set + Set = Best Fit Ellipse

Three or more Features = Best Fit Ellipse
